Hi all, I have two rifles in 6.5x55. The BSA chamber is slightly larger than the Sako. I found this out early on, when a cartridge case that was fired in the former was re-loaded and then became stuck when loaded in the Sako. For some time I kept the two lots of cases seperate, then decided that full length sizing would solve the problem.
Initially I used Lee dies but a couple of years ago bought an RCBS set and now use them. After full length sizing with the RCBS I found that some of the cases were very tight, trying them in the Sako and the odd one I would not be able to close the bolt. I reset the depth on the press and re-sized again. This made some improvement but I was still not happy with the result.
As a final check, I took the old Lee die and set it up in the RCBS press, Re-sized again and Hey Presto, they all chambered sweetly in the Sako.
Question:- Is there an adjustment I have not made in the RCBS die, or is it just not the correct size?
All suggestions appreciated.
